Using the Scanner Tool
Scanner is a network tool that lets you scan all host names in a specified range of IP addresses and verify host status for each IP
address.
You can use the Scanner tool to:
- Resolve multiple IP addresses to host names.
- Determine which hosts are active on a network.
- Find hidden network services like Web servers or ftp.
To use the Scanner tool, do the following:
- Select the Scanner tab.
- Enter in the Address text box IP
address to scan (for example,
18.181.0.25).
- Set in the Options dialog box any of the options you want to use:
Threads
The number of simultaneous threads that are used to run the scan.
Forward
When this option is checked, the Scanner tool scans all host names in
ascending order by IP address.
Verify
When this option is checked, the Scanner tool
verifies host status for each IP address.
Timeout
The
number of seconds
the Scanner tool tries a host that is not responding.
Retries
The number of attempts the Scanner tool tries a host that is not responding.
Port
When this option is checked, the Scanner
tool verifies the open/closed status of the port you specified for each IP address.
Protocol
The network service protocol.
Tip: You can choose both port and protocol from the
current list of
network port numbers.
- Click the Start button.
The Scanner tool scans the range of IP addresses. The results of the scan appear in the
Hosts area.
During the scan, the Start button toggles to Stop. You can click
Stop at any time to stop the scan.
Tips:
- To disable multitasking, set the Threads
number to 1.
- You can right-click the Hosts area to
display the pop-up menu.
Note:
Adjust the Threads number according to your
system. Higher values result in faster scans but require much more memory.
